Greetings. According to the wiki (http://new-wiki.freenetproject.org/Status): "Windows installer - We could do with a more active maintainer, and we definitely need more testers (with different windows versions) for it."
If that's still the case, I would like to offer my assistance. I have a ton of experience writing installers for most versions of Windows. I also have access to various versions of Windows in virtual form that I can use for testing. Let me know if I can be of any help as a Windows installer developer/maintainer. Regards, Jeff Rivett
